This bulletin illustrates and describes some of the more important stamp- 
mill accessories manufactured by this company. It is intended as a supple- 
ment to Bulletins Nos. 119, 121 and 124. in which are described Stamp Mills, 
Rock Crushers and Crushing Rolls and Machinery employed in fine grinding 
of gold and silver ores. 

The tremendous advance made in Hydra-metallurgy during the past 
few years has led to a keener appreciation of the value of preliminary amal- 
gamation and concentration, which in turn has led to the introduction by 
manufacturers of mining' machinery, of a varied line of so-called improved 
stamp-mill accessories. In regard to mechanical innovations, we have always 
taken a conservative stand and have preferred to leave to others the recom- 
mending of untried machines, and have confined ourselves to manufacturing 
only those which time and experience have justified in removing from the 
field of experiment. A list of these will be found in this bulletin. 

Within recent years there has been a tendency on the part of engine 
to incline more and more towards fine grinding, particularly in those 
where the ore is to be ultimately subjected to cyanide treatment. Tli 
vantages and limitations of the stamp mill are well known, and while for the 
preliminary crushing - of the ore it stands unequaled, where a particularly 
fine product is desired it is necessary to supplement it with other machinery. 
The machines employed in fine grinding are properly classed in a group 
by themselves and are described in our Bulletin No, 124.

The Ore or Rock Grizzly 




Here is illustrated the end section of a taper-bar Grizzly. Parallel end bars 
are seldom used in making Grizzlys. Taper bars fitted with tie rods and 
spaced with cast iron tapered thimbles provide a gradual increasing space, 
thereby permitting the screened material to pass through the bars without 
choking. 



Heavy taper bar Grizzlys are of the following cross section: 
Top width, 24 m - ■ depth, 3 in.; bottom width. -">* in.

"I" Beam Type 

These illustrations show our several types of four-wheel. "I" beam trolleys. 
Fig. 2 shows the trolley only ; Fig. I, the trolley with triplex chain hoist 
attached, and Fig. 3, the trolley with special chain hoist together with mech- 
anical means for operating the trolley from the floor below. These devices 
have become essential in stamp milling, concentrating, sampling and rock 
crushing plants, and, in' fact, in reduction work of any character where it 
is necessary at times to handle heavy repair parts, make replacements, etc. 
Our trolleys are exceptionally strong built, the side hangers being of 
forged steel, connected together by means of through bolts with gas pipe 
spreaders. Wheels are the only part made of cast iron, the axles being made 
of steel. We furnish this type of trolley in any size from 3-ton capacity 
to 15-ton capacity, and can if necessary design special apparatus of this 
character to meet unusual conditions. 



Overhead Crawls 

This shows our standard four- 
wheel overhead crawl, designed for 
running on flat track for use in 
stamp mills, crushing plants, etc. 
These crawls arc strongly and sub- 
stantially made, the wheels ami body 
being made of cast iron, axl 

steel, and the hunk ol best forged 

Norway iron, Schedule below

Single Rail 
Amalgam Trolley 

A single rail trolley with cage for use 
in stamp batteries. This is a very con- 
venient device, especially in mills having 
more than io stamps. The trolley with 
cage moves on a piece of J/2 x 3 in. iron. 
and the cage is built strong and heavy 
enough to carry shoes and dies for bat- 
tery replacements or a sand bucket when 
cleaning up. This device saves a great 
deal of hand labor and is a convenience 
much appreciated wherever it has been 
placed in use. Specifications, general 
dimensions and sizes are as follows:

Improved "Hendy Challenge" Ore Feeders 




We deem a description of the 
principles involved in and the mer- 
its of their operation to be entirely 
unnecessary, for the reason that we 
have built and sold at least 10.000 
of the "Challenge" Ore Feeders, 
and they are to be found wherever 
mining is engaged in throughout 
the world, from Alaska to South 
Africa, and their use is acknowl- 
edged to be an absolute necessity 
in all quartz milling enterprises. 
From the date of their introduction 
by us we have given special and 
careful attention to details of con- 
struction. 

The principal dimensions of our 
standard feeders are : From floor 
to top of feeder hopper, 81 inches; 
from floor to top edge of table. 47 
inches ; from front face of frame to 
extreme edge of table, 10 inches. 
Width of frame, 38 inches ; depth, 
44 inches. They can be made rod 
or stem feed as may be desired. 

Shipping weight, 800 pounds. 



Improved "Hendy Challenge" Suspended 
Ore Feeder 



As suggested by its 
name, instead of being 
supported from the 
battery floor it is suspended 
on wrought iron bars, fastened 
to the battery and ore bin fram- 
ing; the feeder is "hooked" over 
these bars and can be slid back when 
it is desired to have free access to 
the back of battery ; with this design 
the floor is left clear and unobstruc- 
ted. The hopper is really a continu- 
ation of the ore bin chute. The op- 
erating mechanism is the same as 
that used for the standard feeders. 
Shipping weight, 800 pounds.

Other end of the rope draws it back when the stamp is lifted. 

A brake to prevent the feeder disc from receding is not required, as the 

weight of the ore in the 
hopper, resting on the disc, 
acts as a brake. 

The dimensions are 
practically the same as 
those of the standard

Belt Tighteners 




Fig. 1 Fig. 2 

The illustrations show two types of battery belt tighteners : Fig-, i 
shows the triangular all-iron frame type adapted for use where the drive side 
of the belt is nearest the battery; and Fig. 2, the all-iron yoke type adapted for 
use where the drive side of the belt is nearest the ore bin. 

These tighteners are exceptionally well built, on correct mechanical 
principles, and are each equipped with the necessary chain, ratchet tightening 
devices with hand wheel, and pulley to suit size of belt called for.

Apron Tables For Amalgam Plates 




The illustration above shows one of our standard designs for an apron 

tabic. While these are not ordinarily furnished by manufacturers, it being 

cheaper in most cases to have them made up on the ground, we give this 

illustration for the benefit of our clients as a suggestion of the most ap- 

] method for making these tables. 

As will be seen, the table is fitted with apron castors, each castor having 
its own piece of track iron, made of J$ in. half round steel, 3 ft. long, turned 
the end. By this means the table may be pulled forward away from 
the battery whenever it is desired to make repairs, thus avoiding the necessity 
of having the mill man walk over the top of the tables and run the risk of 
injuring the amalgamating plates. 

When the table is ready to receive the copper plate, in order to prevent 
amalgam or mercury leaks and consequent loss, a good quality of blanket, 
from 4 to 6 inches wider than the width of the table should be first laid on the 
table top, with the edges turned up. The silver-plated copper plate should 
be placed on top of the blanket and then a piece of quarter-round beading 
should be tacked to the sides of the table. The blanket forms an effective 
means of making a mercury tight joint and will, we believe, give excellent 
satisfaction wherever it is used. 

Below will be found specifications of iron work for castors, track iron, 
and nails for apron tables.

The above illustration shows our automatic wet tailings sampler and 
its adaptability for use in sampling wet tailings after plate amalgamation, 
and also in sampling from the discharge launder of the mill after the entire 
process of extraction is finished. 

Systematic mechanical sampling is absolutely essential in modern mill- 
ing practice and is far superior to hand sampling in every way. 




Automatic Tailings Sampler as Used in Sampling Tailing- 
After Plate Amalgamation 

In the preceding and also in the following illustration may be seen the 
sampling trough, which, when in operation, waves or rocks back and forth 
automatically, thereby cutting the discharge from the lip of the amalgam 
trap evenly through its entire width, thus depositing an accurate sample 
into the pail or other vessel set below the discharge pipe.

ment lilK with water. r, thereby automatical!) discharging 
while the other compartment is filling.

Battery After Passing Through an V 

The amount of water fed into the tipping bucket of the sampler may 
gulated by means of the faucel so that a sample may be taken attto- 
cally, as often as in the judgment of the operator it appears to be neces- 
sary. The range is often varied from one per minute to as few as one 

everv two hours.

An improved form of an amalgam trap, made of cast iron, with guides 
for the wooden baffle plate, as appears in this illustration. The function of 
this device, when placed at the end of battery sluice plates or the launders, 
is to catch any amalgam or quicksilver which may have become detached 
from same, and would pass off in railings unless this or a similar device 
were used. The overflow is carried off by an opening to the laundei 01 
through a tailings sampler. 

The cock provided at the base is for draining off the quicksilver or the 
amalgam caught in the trap.

Hydraulic Cone Classifiers 





Here is illustrated our standard type of hydraulic cone classifier. 

The classifiers are vital necessities in every mill where sufficient water 
is available for their operation and also where concentration is part of the 
ore dressing process. Classification in one form or the other as a step prior 
to concentration is now universally practiced in all modern mills, and as a 
result has made a substantial increase in the percentage of extraction. 

We manufacture these classifiers in five sizes, as follows :

Vezin Automatic Samplers 





Fig. I shows our standard Vezin type automatic dry sampler, and Fig. 
2 shows an outline drawing of same with dimensions scheduled for the con- 
venience of engineers and mill builders. This sampler is probably the best 
known of any of the many devices for the purpose that have been placed upon 
the market within the last few years. As is shown in the illustration, our 
samplers are of the enclosed type, in order to prevent dust and small particles 
of ore from getting out when the sample is cut. The sampler is strongly 
constructed of iron and steel, and with proper attention should require a 
minimum of repairs. We furnish this sampler in three sizes as scheduled 
below. Prices named include iron work only as shown in the illustration.

Clean-up Barrel 




These barrels are used when a clean-up of battery is to be made after a 
mill run, after which, much valuable amalgam is found in the mortars mixed 
with quartz, iron and other substances. This material is collected and placed in 
the barrel in which additional quicksilver is added. Inside of barrel is placed 
cast iron balls, cobble stones, or any heavy unyielding substance. The whole 
mass is thrown in agitation by the barrel revolving, thus grinding the ma- 
terial and allowing the quicksilver to mingle with the amalgam and separate 
same from the worthless material. We make our clean-up barrels with the 
cylinder and ends, also the trunions, cast in one piece ; this has the advantage 
of being free from joints and preventing any leakage of quicksilver. The 
charging opening is shown by cut on top of barrel and is secured by cross 
bar and T bolt ; opposite this opening a hole is tapped to be used for the 
amalgam discharge. 

The barrel is furnished complete, with two bearings, cast iron balls, tight 
and loose pulleys, but without woodwork or bolts for same. 

Our standard sizes and weights are given below.

Batea 




Code Word— Haifa 

This illustrates the "Batea," or what might be called a large miner's 
pan, mechanically operated. It consists of a round cast iron pan, 48 inches 
in diameter and 4 inches deep, with two lugs equidistant from the center, 
cast on same for attaching suspension rods ; opposite these at the front end 
is a discharge spout ; under this spout the pan is supported by a roller. 

The pan is made concave on bottom and a plug is inserted at the lowest 
point, which can be removed when cleaning up. At the suspended end the 
pan is driven by a horizontal shaft, to which is attached the driving pulley, 
16 inches diameter, for 4-inch belt ; mitre gears connect to a vertical shaft 
on the upper end of which is a crank which gives a gyratory motion to the 
pan, which has the effect of collecting the quicksilver and amalgam in the 
bottom of the pan and allowing the lighter materials to pass off on top and 
through the spout. 

The driving pulley should make about 100 revolutions per minute. 

One horse-power is sufficient for driving same. 

Weight of iron work, 1,250 pounds.

Spiral Sand and Tailings Pumps 




* 



Joshua Hendy Iron Works SF.Cai, USA * 



Illustration above shows two views of our spiral sand pumps, which have 
been found to be the simplest and most durable pumps for elevating battery 
sands, pulps, slimes, tailings, or, in fact, any gritty or sandy liquid. The 
speed of the pump runner being only about 20 revolutions per minute, the 
power required is very slight, not exceeding in most cases from 1 J 2 to 2 
horse-power. The maximum lift for the 54-inch diameter pump is 22 feet, 
so that if greater lifts are required it is necessary to use two or more pumps 
placed one above the other. All of the standard sizes are given below for 
the convenience of engineers and mill operators. The countershaft projects 
beyond the pump box 2334 inches for pumps Nos. 1. 2, 4 and 5, and 253/2 
inches for all of the others. Xot le"ss than 20 inches should be allowed for 
the distance that the discharge pipe projects beyond the pump box on the 
side opposite the countershaft. Overall dimensions given in the schedule 
are of the pump box only. Pumps are furnished complete as shown in 
illustration, including pump box.

Horizontal Bullion Retort and Melting Furnace 




A front view of retort setting, showing the melting furnace in section, 
and a side sectional view of retort setting; this is the usual method of set- 
ting our horizontal retorts with a melting furnace placed on one side of 
setting. The fire front is fitted with retort, fire and ash pit doors; opposite 
the retort door a crane is swung for convenience in handling the retort cover 
and amalgam trays. The retorts, except the larger sizes, are cast with lugs 
on the sides which support retorts by resting upon the side walls of furnace, 
the larger sizes have separate bearers. The condenser is made of gas pipe 
from 4 to 6 inches diameter, through which the condenser pipe proper runs 
to the condensing tank. The fittings, furnished with a standard retort, con- 
sist of fire front complete, with anchor bolts, grate bar bearers and grates, 
retort with cover, clamp and trays ; also cast iron sleeve for protecting con- 
denser pipe, condenser pipe and condenser, buckstays and tie rods, damper, 
cast iron stack plate and stack, and if melting furnace is desired, it will 
require, additional to the above, grate bar bearers and grate, melting furnace 
top and covers, ash pit door, anchor bolts and damper.

Faber Du Faure 

Melting Furnace 




Code Word — Haupt 

The Faber Du Faure furnace, as illustrated above, is used principally 
in cyanide plants for melting zinc precipitates, but is also adapted for dis- 
tilling dross in silver, lead and zinc smelting plants. The particular advan- 
tage of this type of furnace is that it may be tilted by means of a worm, 
worm wheel, and hand wheel, enabling the operator to pour bullion from the 
crucible without removing the crucible from the furnace. 

The furnace consists of a cast iron frame mounted at each end on 
trunnions, which rest on heavy cast iron stands. Furnace is lined inside 
with fire brick and is fitted with the usual grate bars when designed for use 
with charcoal or coke as fuel. It may also be adapted for oil. distillate or 
gasoline, as desired. 

The furnace is fitted with a cast iron outlet, which should be brick or 
fire clay lined, and connected to the smokestack, as shown, for the discharge 
of the fuel gases. 

A pot-shaped black-lead crucible is used in the furnace, which may be 
replaced as often as necessary.
